There ya go.. 20/30% or 35, depending on where you are (Sarasota county is 30%, which I'm from). I have 10% all around, dark as crap at night, makes reversing very hard. I'm physically leaning out the window to see stuff. It's not points on the license. That's like saying wrong color headlights, or a hole in the exhaust gives points. Points are for moving violations.
If you don't like people looking at you, and you have a car color that will accept it, look into mirror tint. 40% tint is still SUPER reflective. And legal.
